    Anyone running high RPM's yet (VTECH?)

    Hi All,

    Is anyone running their Sparks in the 8600-8800+ RPM range yet with a remap etc? (Not turbo)

    If so what speeds are you getting and are aftermarket valve retainers/shims required?

    Can get mine over 8100. Testing a few different props. Still nothing over 8100

    Would be interesting to see how what speed that rpm gives on a correctly pitched solas prop with intake grate and ride plate etc

    I was going to do the grate and prop but haven't seen much of a gain from others... But repitch will help ...

    Try lift the hook out of the ride plate to gain more top speed...

    You need velocity stack for na performance at high rpm.

    Theres a lot of talk about people getting these Sparks to 58mph + but no actual proof nor details of how they did it.
